Natural solar drying is a practical method for removing moisture from agricultural products. However, various issues arise in such processes, such as bird, insect, or other animal attacks, fungal attacks, unexpected changes in weather, low or prolonged exposure to the sun, dust mixing, and so on. These problems can be resolved by utilizing a solar dryer. This research is based on the development of a thermally efficient indirect-mode forced convection solar dryer for Bangladesh's rural communities. Our preliminary focus in this article is to design a solar dryer for the rural areas of Bangladesh and evaluate its performance at selected locations through simulations. Through the simulation process, the airflow, temperature change, and loss across the drying chamber were observed. Usable mesh fineness value for simulation, usable process for simulation and validation was found. Observations regarding the change of airflow in the three-axis and outlet temperature change are included in the results. The process and requirements of designing a solar dryer were presented throughout this study.
